Defrosting Food Challenges

• Duration

− Air or water methods take hours; inconvenient

• Attention

− Continuous “hovering” to monitor progress increases inconvenience

• Food Safety

− Bacterial growth risk when surface temperature exceeds 40F/4C

• Quality

− Hot spots and cold spots when using conventional microwave oven

− Moisture loss reduces nutritional content

NXP Smart Defrost Solution: How Does It Work?

Illustration: Concept Smart Defrost Cabinet

• Low frequency electromagnetic waves pass completely through food

• Molecule rotation and collisions create friction heat

• Heat propagates through food

Solid state RF defrost solutions from NXP are safe and fast

NXP Smart Defrost Solution Features and Functionality

• PSU – power supply to convert wall power to

useable DC voltages

• RF – creates the energy used to raise food

temperature

• Smart Tuning Unit (STU) – intelligently

adjusts operation for properties of the food

within the defrost chamber

• Electrodes – provide the delivery of energy

into the defrost cavity

• Cavity – shielded, enclosed space for

defrosting frozen food

• Host Control – main appliance control and

user input interface

Positive Implications for Food Producers and Consumers

NXP Smart Defrost Solution

enables healthier frozen food

options for consumers without

sacrificing convenience

Frozen Fruits &

Veggies Aren’t As

Nutritious As Fresh

The FDA found that there is

no difference in nutrition

between frozen and fresh

produce

Frozen Food Myths

All Frozen Foods

Contain Preservatives

Food can be ‘flash frozen’ to

preserve nutrition and

preserve fresh foods

Frozen Meals Are Not

Healthy

Fresh ingredients can be used

in prepared frozen meals.

Effective defrosting preserves

their moisture and nutrition

while making the food ready

for consumption or cooking

Frozen Meals Aren’t

Environmentally

Friendly

Frozen food is an economical

means to storing food without

risk of spoilage. An effective

defrosting solution can reduce

food wasted by spoilage
